If the universe is so big, why won’t it fight me?

I appreciate the deep dives on this channel... great vids, but I'm also a little surprised at the "absolute" way some of this is presented. We are still pretty limited in our knowledge, so much of this is a scientific guess (or theory).

@nycbearff

If something in the universe has been seen or measured - especially if it has been seen or measured by multiple teams using different methodologies, and so the probability of it being a fact is high - then it's not just a guess, it can be treated as a fact. Prof Lincoln tends to do videos about aspects of the universe that have been thoroughly tested out - and everything he talks about in this video has been thoroughly tested. So yes - you can talk about those things as facts. If you've got the training and the equipment, you can test them out yourself, you don't have to take his word for it. That's what's so good about science, good scientists are very clear about the data and methodologies they used and the probability of their claims being true. And any lab in any country can repeat the tests and check the claim for themselves - it's not a matter of opinion or belief. He's also explicit about things we don't know, and things we think are true but have not been tested exhaustively yet. But this video is about well verified facts.

@@nycbearff I hear you and for the most part I agree... that's why I like this channel, but to say everything in this video has been thoroughly tested out and proven as fact is not a great scientific statement. For example, at the beginning of the video the age of the universe is mentioned and Prof Lincoln states "if you take that number as a given" then references another video. A better statement is "we assume the age of the universe from what we currently know." And that's what I'm pushing on... our knowledge is far more limited than we like to think... our universe could be way older... we are simply relying on our current methods of measurement and we all know how much things change as technology changes. So to recap: my push was on how absolute some of the things were presented that are only "absolute based on our current set of measuring tools and knowledge base"... that moves things from fact back to theory, where science operates best. My guess is, if pushed, Pro Lincoln would agree, but that tends to make a more cluttered video.

​@ChickensFTW Well, nothing can travel faster than the speed of light in space is the law. But space itself can travel faster than the speed of light. And since the Universe as a net is expanding that means that space itself, not as an object in space, it is able to surpass the speed of light. Basically stuff can't travel faster than the speed of light through space, but space itself can surpass the speed of light. And therefore the Universes distances and lifespans don't, at first, match up.

@juggliar A growing universe never made sense to me. If the universe grows the first questions as cliche as that sounds is: into what? Than the answer would be nothing. What is this nothing then? In what way does it seperate itself from empty space. Something that grows has a definite size. It is not infinite. Yet science has no idea what lies beyond the observable. "Because many predictions about the Big Bang have been proven with observational data, we tend to accept it as fact, even though it's still only a popular theory. ... As the story goes, Einstein thought Hubble's theory was flawed. His belief was that the universe was static, rather than steady state."

Thanks Don. This is one of my favourite videos.!! Can someone clarify me this: If CMB radiation that arrives today to us was emitted 13,7 b years ago at a distance of only 42 million ly, does this means that all galaxies we see today (even the most distant) were closer than 42 million ly when the radiation was emited?

@ylu5384

Жыл бұрын

I guess the point in space that those galaxies we can see now occupy would have been well within the 42 million ly radius. But there weren't any galaxies at the point in time the CMB was emitted. The oldest galaxies we can see would have formed several hundred million years after the time the CMB originated from.

Thanks for your answer. Let me ask it in another way: the univers expands in different rates during different periods. Huge expansion at the begging, low expansion till 7/8 b years and accelerate expansion till now. The CMB radiation during its trip from 42 Mly to us today, has found all these expansion rates, that made it last 13,7 b years. During the first period, did the radiation got away from us due to the high expansion and in the other late periods make up lost ground?

Beginning of the universe is such a wonderful mystery!! I Have many questions in this regard. Considering that the present universe we know started with a big bang- which means there was a singularity in the beginning/does it mean there was no space at all? Or with a big bang suddenly the space got created, then what was the volume of that space and the light ( or the ancient light) that was available during that time had a possibility of travelling in a space or has it kind of helped in pushing the space? What if we have ample of light in a very very limited space? Does light always need a space? Another thing that I am also wondering about, is the speed of light has been constant since the very beginning, or it did kind of EVOLVE?

Thank you for this clearly explained and entertaining presentation. I was familiar with most of the ideas in the video and glad to learn new ones.

Since gravity binds us in an expanding universe does that mean technically(or literally) we are moving towards the objects we are bound too? Kind of like having a book and a dot in the middle at the edge of front and back cover… opening the book is like expanding the universe but since the dots must stay the same distance apart(let’s say an inch as the book is an inch think cover to cover) they would travel down until they were both at the middle of the spine of the book. Technically traveling through space and even accelerating as the expansion does.

That was some very, very burned toast.

Greetings from Greece! Very educational video with all these concepts handled and communicated in a way that makes it easier to understand them. If I understood correctly, space is expanding with a speed that is faster than the speed of light? If this is true, they why do we keep hearing that there is nothing faster than the speed of light? Could the answer is that space is not expanding faster than the speed of light, but it seems that way because we and the rest of space are simultaneously moving away from each other in different directions?

They say even they are expanding with space and exceeds the speed of light, to the observer, the relative speed is still less than the speed of light. They call it the relative speed with the observer.

Here's something else that's 'mind-blowing'. Scientists often speak of "Time and Space" as if both had existence. Time has no existence. It is merely a convenient metric to measure the relative position of objects with regards to each other. It is rather like Trigonometry in that regard -- no independent existence, but very useful as a tool to measure things. This is why time travel will never be possible. To go back one second in time, something would have to rearrange all the particles in the universe to their position "1 second" ago. It would also have to rearrange all neural connections in all sentient beings in the universe to their previous state 1 second ago. Have a great 1 rotation of earth on its axis!

Time is relative, and the faster one travels toward the speed of light, the slower time passes for the person travelling relative to a body at rest or travelling slower. This has been tested and proven with atomic clocks leaving one one earth and speeding one up into space. So, of course not time travel as you are correct going backwards is not possible (though some theories try and work it), per se, but one can travel into the future by travelling faster relative to Earth's viewpoint.

What changes in these experiments is a highly localized relationship between movement of atomic particles on one 'clock' versus the other. It has no impact whatsoever on macro 'time/space'.

Let me run a idea that I came up with. Through out time on this earth, we’ve had giants that roamed the earth. As we evolved we apparently got smaller, yet smarter. We learned a lot about ourselves. Our bodies are actually energy, our brains operate on electrical impulses which sends information to all parts of the body, we get our energy from the food we eat, the sun, and as we lay down we can recharge our batteries to live and operate for another day. Let’s take a look at the simplest theory of the box in box. Suppose what you see is actually the inside of the father/gods brain matter. We are just living within, thus we may also have mini universes living and thriving within us. As for the speed of light as it relates to the universe that could very well be the thoughts of the creator. Think about this, when you want to move any part of your body, how long does it take for your brain to send those electric impulses to your muscles to move them? So the box theory could relate to we are the body living within another body. If indeed what you see in space is actually the inside of the creators brain, we also have a universe living within our brains as well, thus touching on another theory of the multi-verse.

I agree with your assertion that it is as much of a nonsense question to ask what is outside of the Universe as it is to asking the nonsense question, "What is South of the South Pole?" as the South Pole is the most southern point of the globe, by definition. There cannot be anything South of the South Pole as there cannot be anything outside of the singularity. As for the Physical Universe...The singularity always existed as a singularity and will always exist as a singularity, the singularity in which we are existing within, as energy can neither be created nor destroyed, but merely transformed. As for the terms "matter", "place" or even "time"? Well they could not exist before the expansion of the singularity. as mass, distance, and time manifest as the direct result of the energy of the singularity being slowed down from Light Speed. (Run the Einstein-Lorentz Special Relativity transformation equations "backwards". I can develop the math, here, if you want. It is simple with one's understanding of the concept of the Limit. But it does take me some time.) Of course we do live inside of the ever expanding singularity and it is an appropriate question to ask when the expansion event happened with respect to time. And that expansion event is what is understood as "the beginning" to many...although somewhat erroneously perhaps.
